The answer is 63

Each man has a wife so, 7+7=14.

And then each wife has 7 children, so, 7x7=49

then you just add the children to the men and women and get 63

So, the answer is 63.

Melanie made contributions to a ROTH IRA over the course of working 34 years. Her contributions averaged $3,750 annually.

aleksklad [387]

We assume that we are asked of the monthly contribution made by Melanie to a ROTH IRA. The give data are below:
Period = 34 years * 12 months = 408 months
Total contributions = $3,750
Solving for the monthly contribution, we have the solution below:
Monthly Contribution = Total contribution / period
Monthly contribution = $3750 / 408
Monthly contribution = $9.2

The answer is $9.2 monthly contribution.

The area of two similar triangles are 50dm^2 and 32dm^2. The sum of their perimeters is 117dm. What us the perimeters of each of

Kay [80]

Answer:

Perimeter of one triangle is 65 dm

Perimeter of other triangle is 52 dm

Step-by-step explanation:

Please remember the concept

If sides are in the ratio of a:b

Then the area in the ratio of $a^{2} :b^{2}$

It is given sum of their perimeter is 117.

Let the small triangle has perimeter as x.

So, perimeter of big triangle is 117-x.

So, we can set up equation as

$\frac{50}{32} =\frac{x^{2} }{(117-x)^{2} }$

Cross multiply

50(117-x)^2 =32x^2

Expand the left side

50 $(13689 -234x+x^{2} )$ = $32x^{2}$

Distribute the left side

684450-11700x+ $50x^{2}$ = $32x^{2}$

Subtract both sides $32x^{2}$ and rewrite it $18x^{2} -11700x+684450=0$

Solve this quadratic for x.

Divide both sides of the equation by 18 to simplify.

$x^{2}$ -650 x+38025=0

Now, if possible let's factor

Find two integers whose multiplication is 38025 but adds to -650.

-65 and -585 works.

So, we can rewrite it as

(x -65)(x-585) =0

Solve them using zero product property

x=65, x=585

So, x=65 works here.

So, perimeter of one triangle is 65 dm

Perimeter of other triangle is 117-65= 52 dm

15(d+7)=4(d-4)+11d answer?

Viktor [21]

Answer:

Step-by-step explanation:

Factor out to simplify:

15d+105=4d-16+11d

15d+105=15d-16

subtract 15d from both sides

105=-16

this means that there are no solutions for d

At the beginning of football season, Coach Carnes takes inventory of the team equipment to see what he needs. He counts 24 footb

Leviafan [203]

Answer:

Step-by-step explanation:

To solve this, lets first find the number of footballs he still needs:

75-24 = 51

Now to find the number of packages, divide by 4, since there are 4 balls per package:

51/4 = 12 Remainder 3

Since there is a remainder, and the Coach MUST have at least 75, then we need to add a package to include the remainder:

12 + 1 = 13 Packages
